Abstract

In order to solve the problems of short service life and insufficient catalytic activity of traditional DSA electrodes, dimensionally stable anodes (DSA) were modified by co-doping antimony-tin oxide (ATO) with different rare earth elements. The experimental results show that when the doping amount of ATO is 2.5 g/L, the optimal doping ratios of rare earth Ceα+、Ndβ+ and Laγ+ are 50∶1, 100∶1 and 25∶1 respectively, and the electrocatalytic performance is: ND-ATO-DSA >ATO-DSA> CE-ATO-DSA > LA-ATO-DSA. The effects of rare earth doping on the microstructure, crystal phase composition, surface element state and electrochemical behavior of the electrode were systematically studied. The results show that rare earth doping significantly affects the electrocatalytic performance of the electrode by regulating key parameters such as grain size, adsorbed oxygen content, hydroxyl radical generation capacity and oxygen evolution potential of the electrode.
